Assembly Speaker Carl Heastie is fond of posing as a post-Shelly Silver beacon of sunlight, a guy who’s brought real reform to the Legislature. Yet his actions point the other way.

The latest example is his decision to start spending Democratic Assembly Campaign Committee funds on incumbents facing primary challenges. ’Til now, the DACC has only spent on general elections — that is, against Republicans, not other Democrats.

Talk about blows to democracy: The primary is often the public’s only real chance to oust an incumbent — because one party’s voters vastly outnumber the others’.

(Of course, the speaker’s plainly not all that fond of democracy, as shown by his success in installing a new Bronx DA without giving the voters a chance to weigh in.)

Note, too, that if reformers still manage to get a new face into the Assembly, these campaign funds give the speaker another way to legally bribe the new guy to play along with the establishment.

Mainly, though, it will further entrench incumbents (on top of their other vast electoral advantages).
